The UN is shocked by reports of slavery in Libya. Refugees are sold in auctions every week. Most of them are African. Some have their kidneys removed. The UN is "horrified" by this. It has asked for an investigation into the reports. It wants quick action, to bring the criminals to justice.

Experts say this is a modern-day slave trade. It is like, "one of the darkest chapters in human history, when millions of Africans were…enslaved…and auctioned". The UN said: "Slavery has no place in our world." Slavery is a terrible abuse of human rights. It is a crime against humanity.
